Claims.

1.9; time maintain the traveler in a constant position relative to the spool or bobbin to thereby. afford aneven and uniform thread-tension and reduce to a minimum. the tendency of the thread to break.

Another object of the invention is the provi- V sion of atraveler which is so designed as to facilitate the threading operation without removing the traveler from the ring, as well as to so guide and direct the thread to and from the traveler as to eliminate its tail-whipping.

Other features of the invention reside in the construction and. arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a fragmentary sectional side view of a spinning machine showing my traveler and ring applied thereto. Figure 2 is a top plan view of the spinning ring and bar traveler embodying my invention. Figure 3 is an enlarged cross section thereof taken on line 33, Figure 2. Figure 4 is an enlarged fragmentary cross section taken on line 4-4, Figure 2. Figure 5 is a perspective view of the bar traveler, showing the manner of engaging the thread therewith.

Similar characters of reference indicate corresponding parts throughout the several views.

In spinning machines of the character to which my invention is particularly applicable, the threads to be twisted are delivered by feed rolls (not shown) to a take-up spool i ii and traversing the Same is a vertically-reciprocating bar I i, the spool extending through an opening l2 in the bar.

Mounted on the reciprocating bar l I surrounding the take-up spool is a supporting member or holder 13 for the spinning or traverse ring it upon which the bar traveler, indicated generally by the numeral I5, is adapted to revolve. Rising from the base portion of the supporting member 13 is an inner annular guard flange or neck it which is spaced from the opposing inner edge of the spinning ring M to provide an annular channel I! for receiving the depending legs of the bar traveler in the manner shown in Figure 4.

Preferably formed integrally with the supporting member l3, and rising therefrom in spaced concentric relation with the annular flange I6, is an outer annular flange I8 which is provided adjacent its lower end with an internal seat or shoulder IS. The spinning ring I4 is removably fitted within the outer flange l8 of the supporting member in spaced relation to the inner flange it thereof and has a depending attaching rim or flange 2Q fitted snugly within the annular flange i8 and abutting at its lower edge on the seat 2i to support the spinning ring in a level or true running position. For the purpose of holding the spinning ring in its operative running position within the supporting member or holder I3, I provide a split-ring clamping member 2| which is adapted to be detachably fitted within the annular flange 8 for bearing contact with the top side of the spinning ring in the manner shown in Figures 3 and 4.

The spinning ring may be made of any suitable and well known material, being provided on its underside with an outwardly-inclined bearing face 22 for the bar traveler, while rising above its plane the ring has an annular wall or flange 23 which extends above the top edge of the guard flange E6 of the supporting member l3 and whose inner periphery constitutes a substantially upright bearing face 24 for the bar traveler. The

inclined bearing face 22 of the ring is spaced above the opposing top side of the supporting member 93 and this space communicates with and forms a lateral continuation of the annular channel I! for receiving the legs and bearing arms of the bar traveler.

The bar traveler I5 is constructed of steel wire and preferably shaped in the manner shown in Figures 2, 3 and. 5, the same being bent substantially U-shaped to form a thread-engaging bar 25, legs 26 depending from the ends of the bar and arranged to extend freely in the annular space or channel I! formed between the neck It and the ring-bearing flange 23, and extensions or hearing arms 2'! projecting outwardly through the lower end of the legs and adapted to enter the lateral continuation of the channel I] into more or less hook-like engagement with the ring, the arms bearing against the bearing face 22 of the ring in the manner shown in Figure 4. By preference the cross bar of the traveler, as shown in Figures 2 and 5, is bent or deflected inwardly from its opposite ends into substantially the form of a wide V, so as to subtend an arc of the inner edge of the bearing ring Hi, the resulting apex portion of the cross bar overhanging and extendshaped cross bar terminates in an integrallyformed thread-guiding loop which preferably depends therefrom into substantially inverted T- shaped form, and includes a neck portion 28 forming a continuation of the adjoining V-portions of the cross bar 25 and .a lower enlarged,

portion 29 which extends uniformly on either side of the neck and Whose wire parts or'components are in the corresponding vertical planes intersecting the V-portions of the cross bar, as 'depicted in Figures 2 and 5. From the foregoing, it will be understood that the thread-guiding loop is formed from one length of wire with the bar traveler and DlOduced by reverse bends consisting of companion inner bends 36, 39 and outer bends iii, the latter and adjoining wire portions serving as guards to maintain the thread coupled with the traveler and accidentally preventingits displacement from the traveler. In threading the traveler, the thread from'the take-up spool is guided around the bend 33*, which is located at the far or trailing side of the traveler at one side of its apex, referring to Figure 2, and then spans the open neck 28 of the loop and thence is engaged With the companion bend 383 forwardly of the apex or center point of the traveler cross bar, as seen in Figure 5, from whence it leads to the take-off spool.

By this spinning ring and traveler structure, the ring affords an extensive bearing for the traveler when traveling at high speeds to assure its stable and uniform operation in a constant position relative to the take-up bobbin, and the traveler design itself insures the thread being coupled therewith both when in operation and when idle, and by its looped construction it can be conveniently threaded Without removing the traveler from the ring.
